An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-53841 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- openclaw (npm): affected all versions; fixed in 2026.5.12\n- openclaw (npm): affected all versions; fixed in 2026.5.12\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-53841/ (Markdown: https://insights.sbomify.com/CVE-2026-53841/index.md)","id":"CVE-2026-53841","markdown":"https://insights.sbomify.com/CVE-2026-53841/index.md","name":"CVE-2026-53841","record":{"aliases":["GHSA-w9hf-3pp7-pvxv","MINI-f6q2-g98f-r763"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenClaw session exporter","requires_auth":"none","summary":"Attackers can execute browser-side scripts when a trusted operator opens an exported session HTML file containing malicious links.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"openclaw","vendor":"openclaw"}],"cvss":{"score":2.1,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-83","name":"Improper Neutralization of Script in Attributes in a Web Page"}],"description":"OpenClaw before 2026.5.12 contains a cross-site scripting vulnerability in exported session HTML that preserves unsafe javascript: and data: links in generated content.
